Abstract
A power control device is configured to control a power circuit that generates an output voltage based on an input supply voltage relative to a ground, and includes a first terminal fed with a common voltage, a second terminal connectable to an application terminal for the ground, a P-type substrate fed with the common voltage, a MOS transistor connected between the first and second terminals and configured with an N-channel MOSFET, and an internal reference voltage generating circuit configured to generate, based on the input supply voltage, an internal reference voltage relative to the common voltage. When the input supply voltage is turned on, the MOS transistor is turned on and thereby the first and second terminals are short-circuited together.
